【摘要】：目的探究核磁共振成像(MRI)与颅脑CT在老年多发性脑梗死诊断中的应用价值。方法 70例老年多发性脑梗死患者,随机分为观察组和对照组,各35例。对照组实施CT检查,观察组实施MRI检查。比较两组患者脑梗死指标检测情况和脑梗死病灶检出部位。结果观察组病灶大小、数量、发病至检查时间、检查时间分别为(8.34±1.63)mm2、(1.89±0.66)个、(0.92±0.23)d、(10.15±1.36)min,优于对照组的(11.41±2.78)mm2、(2.62±0.98)个、(2.01±0.43)d、(18.93±2.65)min,差异有统计学意义(P0.05);观察组额叶、顶叶、颞叶、小脑检出率分别为48.57%、40.00%、62.86%、74.29%,均高于对照组的25.71%、17.14%、5.71%、37.14%,差异有统计学意义(P0.05);两组脑室旁、基底节区、丘脑检出率相比差异无统计学意义(P0.05)。结论与CT检查相比,MRI在检查老年多发性脑梗死中准确率更高,在早期、多发性梗死灶、后颅凹梗死灶、较小病灶等方面检验具有明显的优势。
[Abstract]:Objective to explore the value of magnetic resonance imaging (MRI) and craniocerebral CT in the diagnosis of senile multiple cerebral infarction. Methods 70 elderly patients with multiple cerebral infarction were randomly divided into observation group (n = 35) and control group (n = 35). CT was performed in the control group and MRI was performed in the observation group. The detection of cerebral infarction index and the location of cerebral infarction lesion were compared between the two groups. Results in the observation group, the size, number and time from onset to examination were (8.34 卤1.63) mm2, (1.89 卤0.66) min, (0.92 卤0.23) d, () 10.15 卤1.36 min, respectively. Compared with the control group (11.41 卤2.78) mm2, (2.62 卤0.98) and (2.01 卤0.43) d, () 18.93 卤2.65 min, the difference was statistically significant (P0.05). The detectable rates of frontal lobe, parietal lobe, temporal lobe and cerebellum in the observation group were 48.57 and 40.00and 62.86 and 74.29, respectively, which were higher than that in the control group (25.71 and 17.14). The difference was statistically significant (P0.05). The detectable rate of paraventricular, basal ganglia and thalamus had no significant difference between the two groups (P0.05). Conclusion compared with CT, MRI is more accurate in the diagnosis of senile multiple cerebral infarction, and has obvious advantages in early stage, multiple infarct, posterior fossa infarction, small focus and so on.
